Packages create one or more public contexts. These can be revealed by 
the command:

Contexts["Graphics`*"]

Since you are probably only interested in one of these contexts (and 
simpler packages often only create one context) it is best to pick one 
context and get a list of the symbols it contains, for example:

?Graphics`Shapes`*

Note that not every symbol will be an actual command.

As your question implies, this technique is often more convenient that 
ploughing through the entire package documentation.
